Just read all Model B Raspberry Pi for now on will have 512MB of RAM. Now if Puppy could boot using PupSave file(s) with the core 5 or 6 boot files (Not a full install) and use armhf like the Raspbian OS, that would be fantastic. Oh, and when they get X-Windows to use the hardware video acceleration that would be frosting on the cake.

For me the power of Puppy is not running it from a full install, but I might be in the minority.
